Sisso the swift was found with a damaged wing seven months ago. The little bird has healed, but must learn to fly all over again with some inventive physical therapy. Sisso takes flying lessons suspended from a custom-made sling!

The swift is being treated at an Israeli animal hospital and it is thanks to this ingenious device - which resembles a mobile in a child's bedroom - that he can practise flying.

Fitting snugly into a red tube-like vest made of bandages and gauze pads, Sisso has holes for his head, wings, feet and tail.

A string is fixed to the harness and attached to the ceiling which allows him to whizz around a room at the Ramat Gan Safari Park Animal Hospital without falling to the floor.

However, until the muscles in his weakened right wing become strong enough, he will be kept indoors and in the sling.
